Patent number: 6935608Abstract: A microvalve and a method of forming a diaphragm stop for a microvalve. The microvalve includes a first layer and a diaphragm member to control the flow of fluid through the microvalve. The method comprises the step of forming a contoured shaped recess extending inward from a surface of the layer by using a laser to remove material in a series of areas, at successively greater depths extending inward from said surface. Preferably, the recess has a dome shape, and may be formed by a direct-write laser operated via a computer aided drawing program running on a computer. For example, CAD artwork files, comprising a set of concentric polygons approximating circles, may be generated to create the dome structure. The laser ablation depth can be controlled by modifying the offset step distance of the polygons and equating certain line widths to an equivalent laser tool definition.Type: GrantFiled: June 24, 2004Date of Patent: August 30, 2005Assignee: Lockheed Martin CorporationInventors: Glenn S. Claydon, Ernest W. Balch

Patent number: 5099202Abstract: A phase shift generator receives two input pulse signals and generates two output pulse train signals, each having a 50% duty cycle, which are phase-shifted in a range from 0.degree. to 180.degree. by an amount proportional to the duty cycle of the input pulse train signals and also proportional to the power supply load requirement.Type: GrantFiled: July 2, 1990Date of Patent: March 24, 1992Assignee: General Electric CompanyInventors: Glenn S.

Patent number: 4967332Abstract: A primary side power supply controller includes a full-bridge/half-bridge driver and is capable of being implemented on a single HVIC chip. Control circuitry enables operation in PWM, resonant, and phase-shift control modes. In the phase-shift control mode, a phase shift generator receives two input pulse train signals and generates two output pulse train signals, each having a 50% duty cycle, which are phase-shifted in a range from 0 to 180.degree. by an amount proportional to the duty cycle of the input pulse train signals and also proportional to the power supply load requirement. Dead time circuitry for ensuring that no two switching devices in a half-bridge, or in the same leg of a full-bridge, are conductive simultaneously employs a symmetrical delay circuit which independently delays the rising and falling edges of each signal pulse.Type: GrantFiled: February 26, 1990Date of Patent: October 30, 1990Assignee: General Electric CompanyInventors: Glenn S.

Patent number: 4806844Abstract: An on-chip DC power supply uses at least one series pass element which conducts responsive to a gating signal obtained by clamping an input potential to a preselected polarity and amplitude. A charge storage element serves to maintain an output voltage which is clamped to a predetermined maximum value. An output regulator provides a substantially constant second output voltage at a magnitude less than the output voltage set by the output clamping means.Type: GrantFiled: June 17, 1988Date of Patent: February 21, 1989Assignee: General Electric CompanyInventors: Glenn S. Claydon, Robert P. Alley, William J. Laughton

Patent number: 4694384Abstract: A digital data detector is part of the primary side control electronics in a high voltage integrated circuit for regulating a power supply secondary side output potential; the detector output is responsive to the transitions of digital error data received from the supply secondary side via an electrically-isolated data transmission means. Only the transition edges are utilized by the detector, so that any non-linearity after each transition of the transmission means is immaterial. If the isolation device is a pulse transformer, the transformer core can be of relatively small volume, as full-pulse reproduction is unimportant and pulse saturation is tolerable. A multiplexer allows the primary side control electronics to initiate power supply operation; control is switched to the secondary side responsive to signal edges therefrom being detected by the digital data detector.Type: GrantFiled: December 4, 1986Date of Patent: September 15, 1987Assignee: General Electric CompanyInventors: Robert L. Steigerwald, Kevin C. Routh, Glenn S. Claydon, William H. Bicknell
